Brief summary
Evaluate the safety and outcomes associated between the two treatment modalities
Detailed description
Assess the risk of vancomycin-associated nephrotoxicity and outcomes associated with continuous infusions (CI) versus II dosing in the outpatient parenteral antibiotic therapy (OPAT) setting
Interventions
The CI group will have their total daily cumulative dose of vancomycin converted to a 24-hour intravenous infusion upon discharge - the CI will begin with the first scheduled OPAT dose of vancomycin
Study candidates that are randomized to the II group will continue their current intravenous dosing upon discharge

Intervention model description
To assess the risk of vancomycin-associated nephrotoxicity and outcomes associated with continuous infusions (CI) versus II dosing in the outpatient parenteral antibiotic therapy (OPAT) setting
Eligibility
Inclusion criteria
* Adult patients at least 18 years of age * Receiving Wake Forest Baptist Health Outpatient parenteral antimicrobial therapy (OPAT) services * Will receive vancomycin therapy from Wake Forest Baptist Health Specialty Home Infusion Pharmacy * Planned therapy with vancomycin in the outpatient setting for at least 2 weeks in duration * Prescribed vancomycin with a frequency of either every 12 hours or every 8 hours dosing at the time of enrollment
Exclusion criteria
* Presence of diseases or conditions known to affect the pharmacokinetics of vancomycin: Pregnancy/Ascites/Burn injury/Cystic fibrosis /Weight greater-than or equal-to 150 kg * Pre-existing leukopenia: White Blood Cell (WBC) \< 4,000 x 103 cells/µL
